Workshop Description

  • The purpose of this introductory hands-on workshop is to learn power system modeling & analysis using ETAP software extended to four days in order to cover additional topics.
  • This workshop covers a range of ETAP functionalities used to design & solve various power system practical problems.
  • It starts from utilizing the full capabilities of the software for modeling & managing of the power systems to equipment sizing in steady state and short circuit conditions, motor acceleration scenarios, device coordination, arc flash assessment, transient stability, and user-defined dynamic modeling.
  • One day of this workshop is dedicated to DC Systems Analysis which includes DC Load Flow, Short Circuit, Battery Sizing & Discharge and DC Control Systems. DC systems will cover modeling of various DC components as well as AC-DC interface devices such as chargers, batteries, motors, loads, control relays, coils, contacts, etc. It also covers calculations, operating logics, and sequence-of-operation of the control diagrams along with case studies related to automatic control of switchgears, motors, and other processes.
  • An ETAP workstation is provided for each attendee.

Who should attend

  • New ETAP users and power engineers who wish to increase their skills using the ETAP application to perform system studies.
  • Current users seeking a refresher course.
  • Knowledge of power system engineering concepts is highly recommended for those attending this workshop.
